Weather in Mar del Plata in November
Argentina · 20-year averages, November
A good month. November is a solid month to be in Mar del Plata. Highs average 19.5 °C, lows 12 °C, and rain falls on 10 days — nothing in the month is working against you.
November is the highest-scoring month of the twelve. The nearest rival is December, and the month at the other end of the year is July.
Rain on 10 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C. Across the twenty years measured, the hottest November day reached 28.6 °C and the coldest night fell to 6.1 °C, and the wettest single day dropped 76 mm — roughly 72% of the month's rain in one day.
November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 194 mm against 40 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 106 mm average is a reasonable planning figure, not a promise.
Wind sits around 16.1 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 76%, high enough to notice on the warm days without dominating them.
How November sits in the year
The month is on the way up: 3.3 °C warmer than October, and December adds another 3.3 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in November
14.2 hours of daylight, gaining 0.9 hours across the month. That is between Mar del Plata's extremes of 14.8 and 9.5 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 13.8 °C in November — too cold to swim without a wetsuit. The sea peaks at 19.9 °C in February and bottoms out at 9.7 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May is the trade worth considering — 9 points weaker on weather, and materially quieter.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
November in Mar del Plata versus nearby
If Mar del Plata is one option among several, the nearby comparison is worth making. Buenos Aires is close enough to be a coin toss — 3.9 °C warmer, 2 days less rain. Rosario is close enough to be a coin toss — 9.6 °C warmer, 1 day less rain.
So: November is the answer for Mar del Plata. If it is booked out or priced out, December is the next best thing at 0 points behind, and July is the month to keep off the shortlist.
